Turkey scrambled fighter jets along its border with Syria on Monday after Syrian government forces bombed rebel positions in the frontier town of Ras al-Ain and stray shells flew into Turkish territory, Turkish security sources said.

The security sources said Turkish F-16 jets were scrambled from their base in the southeastern city of Diyarbakir after the air raids on the Free Syrian Army's headquarters in Ras al-Ain.

Shells landed in the Turkish town of Ceylanp&#305;nar, which abuts Ras al-Ain, triggering panic, the sources said. It was not immediately clear whether the shells were fired by forces loyal to President Bashar al-Assad or by the rebels.
